Closing an app causes crash

[radiceta]

Closing thunar leafpad or firefox (maybe others too) thows me back to login. Here is a log:

i think its fixed, may try with up-to-date commit plz? :)

[radiceta]

it seems to be okay. I have not experienced any crash yet. Last few days it was terrible to work with filezilla, which caused crash at many floating dialog windows but now it works fine. thaks.

Still seeing the issue with latest commit only on 64bit Ubuntu 11.10 (both 3.2.0-7-i5 & 2.6.38-11-generic), but does work on 32bit Ubuntu 11.10. xlib-6 (library fails on) is version 1.4.4-2ubuntu1 on all three machines.

@radiceta : Hello,
Maybe you should indent your code:
A '#' followed by a number is considered as a reference to a pull request by Github, so a messsage saying the pull request has been referenced in your issue appears in all the pull requests from #1 to #17 :-)

EDIT @linkdd : fixed

[linkdd]

It seems to be fixed, I close the issue

Not working for me under Ubuntu 11.10 x86_64. Fully updated system today, and did a fresh clone this morning.

I try to close the buddy window under pidgin, and I get a crash. gdb output:

Not fixed for me too. Ubuntu 12.04 x86_64 with the fresh cloned version of wmfs.
Gdb session with the backtrace similar to the @duck 's one.
